IMPROVEMENT vIN MACHINES FOR PRESSING A-ND EINISHING WOVEN FABRICS.

Specification forming part of Letters Patent No. 221,047, dated October 28, 1879; application filed June 17, 1879.

the following is a full, clear, and exact de scription of the same.

My invention relates to a machine for hot-v pressing cloth, in which the cloth is made to pass between a hollow press-box heated by steam and an adjacent pressing-cylinder.

My improvement consists in the combina-- tion, with two or more cylinders and corresponding pressboxes arranged to give a 1epeated pressure upon one side, or successive pressures upon opposite sides, of the cloth, of a carrier-belt, roller, or equivalent device, adapted to receive the cloth from one pressbox and prolong its travel in its passage to the next press-box, wherebya--sufcient timeis allowed for the goods to become cooled before receiving the second hot-pressing, as hereinafter fully described.

In constructing the machinesin accordance with my invention .they may be arranged in various ways.

In Figure l. is shown a verti 'al cross-section, and in Fig. 2 a front view, of a press, with cylinders B and B' land pressing-boxes U and C' lying one above the other. The bores C and C' and cylinders B and B', heilig mounted in the main standardA, receive their pressure by weight- G through the lever combination Il H, acting upon the top pressingbox, C. i'

The two pressing-cylinders B and B' are an ranged to be moved endwise for pressing goods with selvages of different widths and styles, and this movement is accomplished as follows: The shafts z z of the cylinders B and B' run on one side of the machine inlongsleeve-bearings l I, which are provided with screw-threads upon their outer surfaces. Around these sleeve-bearin gs are the worm-gears a n, which receive motion by a worm, s, by means of a handle, and thus change both pressingcylinders B and B' lengthwise. The worm-gears n n and the sleeve-bearings l l are mounted beneath a cover, H, which is combined with the main standard A. Instead of .adjusting the cylinders B and B', the pressing-boxes C and C' can be made movable. The pressing-cylinders are driven from the brush-cylinder shaft W by the gears R' to RG.

The cloth runs over the stretchers J J, brush W, the cross-bars V V, and the roller J' toward Jthe lower pressing-box, C', around the lower pressiiig-cylinder, B, and between it and the upper cylinder, B'; then the goods are held by the support z' toward the apron L, and are led, while cooling off, over that apron, and pass between the upper box, C, and cylinder B' to receive a second pressure. After the cloth is finished here it goes over apron L2, and is folded by the folder T at the bottom board ofthe machine.

In Fig. 3 are two cylinders, B and B', and two boxes, (l and C', mounted one above the other, and on the lower cylinder, B, one, more pressing-box. C", is applied to one side.v

Figs. 4 and 5 represent two cylinders, B and B', and two pressing-boxes, ,C and C', upon the opposite outside surfaces of the two cylinders, the cloth running in the direction of the arrows, similar to that shown in Fig. 3.

The goods,ilying folded upon the bottom board, run over the different rollers and crossbars J J', pass the entering cylinders B and boxes C, to receive the iirst one-sided pressure, then drop, to be well cooled off, upon an endless apron, T, which is fastened beneath the bottoni board of the machine. Now, the cloth goes in Figs. 3 and 4 up to anotherapron, T', from there to the second eylinder,.B', and second box, C', and thence to the receivingroll D. In Fin'. 5 it passes around cross-bars and rollers J J, up to the cylinder B and pressing-box C, then down to the endless apron, and then up around rollers and crossbars to the cylinder B' and boX C', and thence down to the folding-board.

In Fig. 6 the cloth passes from the folds l, on the platform at the left, up to the press'- boX G and cylinder B, thence down below the platform to the belt or apron T, to be cooled ofi, then up upon the eXtreme right of the inaehine, through the stretchers and rollers J J', to press-box C' and cylinder B', and finally down upon the platform again at 2. This construction possesses the incidental advantage of being capable of pressing two separate pieces of cloth (upon one side only, however)l at a time. Thus by shifting the carrier-belt to the left, as shown in dotted lines, one piece of cloth may pass up from on the left of the platform, to the pressing device, and then descend to the belt, (shown in dotted lines,) and pass thence to a roller, and be folded at 3 on a board to the cxtreme left; or, instead of being folded on the left, the position of the apron T may be unchanged, as shown in full lines, and the same cloth wound on a beam, 4, on the eX- treme right. The other piece of cloth may rise from the platform at 5 on the right, and, after passing through the stretcher and rollers J J l and the cylinder and press-box B C', descend therefrom upon the platform again, as at 2, or upon the belt T, to be wound on roller 4".

Fig. 7 shows a vertical cross-section, and Fig. 8 a front view, of a further modification. The goods run to the first boX, C', and pressing cylinder B', around which a met-al pressin g-plate, l), is bent, as described in my patent No. 206,718, and which plate is tightened by tension-shaft L. Between this plate and the cylinderB one side of the goods is pressed; then the cloth goes, to be well cooled oi', over a set of rollers, J J or over an apron toward the second cylinder, B, and box G, which are also provided with a metal pressing-plate, being fastened on one end to the lower part of .the pressing-box C', and tightened by tensionshaft L. Finally, the cloth passes over the leader j to be folded on the bottom board.

Both cylinders B and B receive motion from thebrush-cylimler shaft T by the gears R to BG. The boxes C and C are mounted in the lever-arms D D, and are pressed against the cylinders B and B by the tension-springs F.

In Fig. 9 a continuous press-plate, P, connects the two boxes, andan intermediate roller (which is the equivalent of the apron) diverts and prolon gs the passage of the cloth to allow it to become cooled before going to the next pressing-box.

In Fig. l0 a similar arrangement of the cooling-roller J is preserved between two cylinders and simple subjacent press-boxes.

Fig. l1 shows a machine with two cylinders, B and B, each with their pressing-box C and C', combined with a metal pressing-plate, P, which receives tension by means of the tension-shaft L, the cloth being cooled by an cndlcss apron below.

Fig. l2 shows two cylinders, B and B, and two pressing-boxes, C and C', below them, the cloth being cooled by an apron beneath them.

Fig. 13 represents two cylinders, B and B', havingadonble-actiug box, C, between them, one pressing-box, C, on each opposite side, and one box, C', below each cylinder B and B', with a cooling-apron below.

The cloth moves in the direction shown by the arrows, and the goods pass from one cylinder, B, over the leaders jj toward the otherl pressing-cylinder, B.

From the foregoing description it will be seen that in each case Ihave two pressingfacing operating consecutively upon the cloth with an endless apron, roller, or series of rollers interposed in the path of the cloth from one pressing-face to the other, to prolong the travel of the cloth between the pressing operations, and thus cool it before it is hot-pressed a second time.

When only one or more rollers without au apron is used, as in Figs. 7, 9, l0, the said rollers may be made hollow, and a current of cold water passed through the same to operate, in conjunction with the prolonged travel of the cloth, to cool it and cause it to set before receiving' the second pressing.

Having thus described my invention, what I claim as new is- 1. The combination, with apairof cylinders and press-boxes for giving a repeated pressure to the cloth, of a carrier-belt, or its equivalent, as described, adapted to prolong the passage of the cloth in its travel from one to the other cylinder, to permit it to be cooled before receiving the second pressi n g, substantially as described.

2. The combination, with a pair of cylinders and press-boxes, arranged substantially as described, of a cooling device adapted to operate upon the cloth in transit from one pressbox to the other, to cause the cloth to set before receiving the second pressin g, as described.

The above specication of my invention signed by me this 18th day of December, A. D. 1878.
